AUTO REGISTER.

To all whom it may concern:

Be it known that JOSEPH B. FRANCISCO, a cltizen of the United States residing at Columbus, in the county of B ranklin and State of Ohio, has invented certain new and useful Improvements in Auto Registers, of which the following is a specification.

This invention relates to an improved register primarily adapted for automobile heating systems, and has for its object the provision of a register which will enable the heat of the system to be readily controlled and the delivery thereof to the vehicle governed in accordance with temperatures desired. g

Another object of the invention resides in a register having a casing formed to include a pair of independent outlets, one of said outlets leading into the vehicle proper and the other of said outlets in communication with the atmosphere, the delivery of heat to said outlets being regulated by a pivotally mounted damper plate which when in one position of operation will. serve to direct the heat into the outlet leading into the vehicle and when in the other position of operation will serve to direct the heat into the outlet leading to the atmosphere.

A further object of the invention resides in the specific construction of the damper plate itself and the operating mechanism therefor, the latter being of such character as to enable the said plate to be readily moved toassume its aforesaid operating positions and having means of a positive nature connected. therewith for rigidly maintaining the said plate in its positions of adjustment, and to permit this to be aceomplished in such manner that the vibration or jolting of the vehicle will have no eect upon the adjusted positions of the ate. p Other objects of the invention reside in a register which may be conveniently applied to the average motor vehicle, of simple construction, easy to operate and of economical construction, and formed to prevent the accumulation of f0] .gn matter therein. For a further 1" lerstanding of the invention, reference is to be had to the fol-,

lowing description and to theaccompanying drawing, in which similar characters of refbeingv erence denote like and corresponding parts throughout the several views thereof.

In said drawing:

Figure 1 is a sectional view taken through a motor vehicle and illustrating the application of the register, comprisingthe present invention, thereto.

Figure 2 is a vertical sectional view taken through the register and illustrating more particularly its internal construction.

Figure 3 is a transverse sectional view taken on the plane disclosed by the line 3-3 of Figure 2, and,

Figure at is a detailed view of the damper plate.

Referring more particularly to the details of the invention, my improved register, designated in its entirety by the numeral 1, is primarily adapted to be employed in connection with a motor vehicle 2, for the purpose of admitting heat into the latter from a heating system 3 or, conversely, for the purpose of excluding the entrance of heat into the vehicle. The heating system 3 such that upon the operation of the engine,

air will be forced through the heater and by contacting with the surface of the exhaust manifold thereof, the air will be heated to a sufficient degree to permit theisame to be eficiently employed for the purpose of heating the interior of the vehicle 2.

1 With regard to the s ecific construction of the register 1, means ave been provided whereby the entire volume of the heat from the system 3 may be delivered into the vehicle or if such heat is not desired, the register includes a construction whereby the heat may be directed outwardly from the register without enterin the vehicle. To this end, the register 1 includes a metallic casing 5, which is of such construction as to be capable of being received within an opening 6 provided therefor in the foot board construction 7 of the vehicle 2, the upper marginal edge of the said casing being provided with an out-turned flange 8, which is arranged to be positioned over the margins of the opening 6, and thus to enable the casing to be securely supported from the .foot board.

The casing is of hollow construction and is divided internally into a pair of separate compartments or conduits 9 and 10 by means of a centrally located partition 11,'in which anopening 12 is provided for the reception of a movable damper plate 13, the said damper plate being adapted to control communication between the compartments 9 and 10. The forward part of the compartment 9 is provided with a removable wall '14 from which extends a tubular projection 15, the latter being suitably connected by means of a conduit 16 with the rear or discharge end of the heater 3, whereby the heat of the system 3 will'be deliveredto the said lower compartment 9. The rear portion of the compartment 9 opens directly to the atmosphere, as indicated by the opening or outlet 17, therefore, when the damper plate 13 assumes a position obstructing the opening 12, the heat of the system 3 will be delivered to the compartment 9 and will escape from the register by way of the outlet opening 17, without entering the interior of the vehicle 2 and moreover without heating such portions of the register as are exposed to the interior of said vehicle. ,However, when said plate assumes a position unobstructing the opening 12, the said plate will overlie and obstruct the outlet opening 17 thereby causing the heat to flow from the compartment 9 into the compartment 10, and thence through the grill 18, carried by the upper portion of the casing 5, into the interior of the vehicle so as to effect the heating of the latter or, in other words, to enable the system-3 to deliver. the entire volume of the heat thereof into said vehicle. j

.To govern the operation of the damper plate 13 and to maintain the same in its various positions of adjustment, the said plate is provided with an offset actuating arm.

19 which has its outer end terminated in a knob 20, which is disposed within a recess 21 provided" in the exterior surface of the grill 18. This knob isof such formation that the same may be conveniently grasped by the operator or engaged by the foot for the purpose of moving the plate 13 from one position of operation to another. The pivotal construction for the plate 13 consists in providing opposite edges of the latter with integral studs 22, which are adapted to be received within pockets 23 formed in the partition-11. This construction enables the plate to readily swing about the axis defined by the studs 22 and to enable the openings 12 and 17. to be governed by the common plate 13. Also, the arm 19 is so located with respect to the studs 22 that the knob on said arm will be permitted to freely oscillate without being interfered with in any way by the'grill construction 18. To hold the plate in its positions of adjustment, I employ a U shaped spring 24:, which is suitably secured to certain of the bars of the grill and is positioned so that the longitudinal portions thereof will receive the arm 19. The said arm being provided with laterally extending pins 25. which are so disposed that the upper edge of one thereof will engage with one of the longitudinal portions of the spring 24. and the lower edge of the opposite pin will engage with the outer longitudinal portion of the spring 24. This construction serves to place pressure upon the pins 25 so as to cause the plate to be maintained in any position of adjustment, that is, in either its closed position or open position or at any position intermediate of such closed or opened positions. 'By this construction the degree of heat delivered to the vehicle 2 may be accurately and easily controlled, and the temperature ofthe interior of the vehicle comfortably and readily maintained. By the provision of the spring 24 the various positions of adjustment of the damper plate are to be had, and such positions will be maintained irrespective of the jarring and jolting of the vehicle as will occur in actual operation.

From the foregoing description, taken in conjunction with the accompanying drawing, it will be apparent that the present invention provides a register construction for vehicle heating systems which will be eflicient and positive in operation and may be readily controlled and adjusted by simple .manual operations to insure the delivery of any desired quantity of heat into the vehicle. Furthermore, when the plate 13 is oscillated to assume a. position obstructing the open ing 12, the heat will easily fiow and pass out to the atmosphere by way of the opening 17, and this action will occur without in .any way heating such parts of the regis ter as are located within the vehicle. It will be observed that the register is in open communication with the heater 3 and consequently if any foreign matter should accumulate within the casing 5, the same will be excluded from the register when the open- 1.
